This looks worse then czars pathetics attempts he had once to vector.
Im joking,
You need to work on it, some of the lines don't look smooth enough, and there are too many jagged parts, needs to be also a bit more detail in the face. Go over hair lines also so you get more in depth hair, which brings more detail to the piece. Mouth looks nicely done, bottom of the eye looks weird though.
Alright job, needs improving.
